DENVER (CBS4) – Workers woke up to a frigid morning in the Denver metro area on a day where schools were back in session and people to wanted get to work and school safely.

Winter break is over and those who headed outside got a nice wake-up call with single-digit temperatures. It was the type of cold where it could be felt in the fingertips, even with gloves on — and felt it in the toes with boots on.

It snowed off and on all day Sunday in the metro area. Some people said when they watched the weather from inside their cozy homes they knew they had to be prepared for Monday morning. Mittens, scarves, earmuffs and hats were must-haves.

CBS4’s Lane Lyon spoke with one Regional Transportation District commuter who appeared to be bundled up and prepared for the wait for her RTD bus ride.
